“One-third of the 3,863 reefs that make up the Great Barrier Reef — the largest, most extensive reef system in the world — went through a catastrophic die-off after a searing heat wave in 2016, according to a newly published study in the journal Nature. A bleaching event in 2017 devastated even more of that reef, and the cumulative effects have killed an estimated half of the magnificent system in just two years.”

It’s a quote from the article below, a work that fits in the “doom and gloom” category. But unlike articles about Planet X, the “unavoidable catastrophic” eruption of Yellowstone or the reversal of the Earth’s magnetic poles, this is “real doom and gloom”. Corals around the world are dying at an alarming rate. This can lead to sudden, disastrous effects on the ocean ecosystem (and thus, the entire planet).
